Connecting device to vehicle battery terminals

Abstract

A connecting device applicable to a battery terminal can display the electrical condition, such as the voltage of power and the condition of the fuses of each line. The connecting device includes a main body having a clamp at one end for fixing to the battery terminal, and the other end for carrying a display unit and connecting cables of appliances. The display unit makes the connecting device displayable with electrical conditions directly without the need of using other testing devices.

What is claimed is:  
     
       1. A connecting device applicable to a vehicular battery terminal comprising at least: 
       an electrically conductive main body, having one end formed with a clamp for fixing to the battery terminal and leading power to at least an appliance, and another end formed with a carrier for cables;  
       a display unit, mounted on said main body, comprising:  
       a circuit board;  
       a plurality of connecting pins, inserted into the carrier for linking the battery power to the circuit board;  
       a display mounted on the circuit board, showing the electrical status of the battery power; and  
       a window, made of a transparent material and mounted on said display unit for protecting and showing the same.  
     
     
       2. A connecting device applicable to a vehicular battery terminal as recited in  claim 1  wherein the carrier is formed with a recess for mounting the display unit. 
     
     
       3. A connecting device applicable to a vehicular battery terminal as recited in  claim 1  wherein the carrier is formed with a plane at the top of the main body for mounting the display unit. 
     
     
       4. A connecting device applicable to a vehicular battery terminal as recited in  claim 1  wherein the carrier is formed with a plane lower than top of the main body for mounting the display unit. 
     
     
       5. A connecting device applicable to a vehicular battery terminal as recited in  claim 1  wherein the display is a liquid crystal display. 
     
     
       6. A connecting device applicable to a vehicular battery terminal as recited in  claim 5  wherein the display unit further comprises a plurality of light emitting diodes.
